| Research Abstract |
The effects of non-linear dynamic soil-structure interaction of spread foundations were discussed where "Input loss by base-slip" and "Response reduction factor " were proposed through shaking table tests and non-linear seismic response analysis considering base-slip of spread foundation. In case of pile foundations, the effects of non-linear dynamic soil-structure interaction were studied through field investigation of damaged buildings and microtremor measurements and aftershock observation of 2011 Tohoku Earthquake. In case of pile foundations, numerical analysis and introducing the effects into design technique will be discussed in more detail in the future.
